What 5 enzymes are found in grapes? What does each of them do?

Question

I learned that enzymes play a big role in winemaking. But most of the enzymes I've read about are from the same families, Pectinase and Glycosidases which almost serve the same purpose.

Answer 1

The enzymes are:

1) Pectinase: Used to break down the polysaccharide pectin, which forms cell walls.

2) Xylanase: Breaks down xylan, another polysaccharide found in plant cell walls.

3) β-Glucanase: breaks down polysaccharides found in the membranes of yeast cells.

4) Protease: Used for protein stabilization

5) alpha-l-rhamnosidase: releases aromatic compounds

There are more enzymes than these invovled in wine-making, but there are some of the more important ones.
